Reading Time: 2 minutesOne of the interesting message from the Open Storage Summit EMEA 2012 is that (for Nexenta and other several companies/organizations) the ZFS if probably the perfect filesystem for storage systems. For Nexenta this is a core part of their NexentaStor solution and products and their are still thinking that is (also today) the best choice. But what is ZFS? It’s a combined file system and logical volume manager designed by Sun Microsystems on 2005 for OpenSolaris. One really interesting aspect is that ZFS is implemented as open-source software, licensed under the Common Development and Distribution […]

Reading Time: < 1 minuteYesterday, Nexenta® Systems, at the start of its OpenStorage Summit EMEA, announced the official release of NexentaVSA for View, a breakthrough solution that expands Nexenta’s proven ZFS-based storage software into virtualized desktop environments. A result of Nexenta’s strategic partnership with VMware, NexentaVSA for View simplifies several task of a virtual desktop environment: Deploy: The VDI Deployment Wizard gives administrators the capability to create NFS / ZFS storage from local ESX storages of all clustered ESX servers and, subsequently, create virtual desktops based on this automated (created) storage. Measure: Unprecedented performance testing, provided through NexentaVSA Performance […]
Reading Time: < 1 minuteThe official VCAP5-DCD exam has been released some days ago and there is the relative web page with several information about it and, of course, the blueprint. And also there are other site with useful study guides and notes: VCAP brownbags Gregg Robertson’s VCAP5-DCA & DCD resource page Scott Vessey’s VCAP5-DCD resource page (actually contains only generic information) Ray Heffer’s VMware VCAP5-DCD Study Guide & Notes page Steve Dunne’s VCAP-DCD 5 – Study Pack VCAP-DCD | Objective 1.1 | Gather and analyse business requirements
Reading Time: < 1 minuteFinally, after the beta period and a long waiting (first time that beta results were out before the exam goes live), the VCAP5-DCD exam is now available. All information are on the official web page. It also confirmed the rumors that, for a shot period, all VCAP4-DCD could upgrade to v5 without the need of VCP5… Nice but unuseful… I think that most has alreay upgrade before the 29th of Feb… So an exam discount (IMHO) was a better option. As usually, for VCAP exam, you need to require a VCAP5-DCD Authorization, that is still […]
Reading Time: 2 minutesToday a new traing video has been added in the Backup Academy web site: “Basic principles of backup policies” by me :) In this lesson I will explain what is a backup policy and also give some information about the flow and the process to design a backup plan. Then I will detail some aspects of a backup policy, like What, Where and How. The purpose of this lesson is just give the bases of some concepts. For deep technical details on specific argument there are other lessons in the Backup Academy. Basic principles of […]
Reading Time: < 1 minuteIn the previous post we have discuss on how convert from VHD (used for example in Microsoft Hyper-V) to VMDK format (used in VMware products). Now let’s see how to convert from the other side. There are several tools to make this V2V operation:
Reading Time: < 1 minuteAs you probably already know a VM is incapsulated with a set of files that define VM properties and objects. Some of those files are the virtual disks files and each vendor use its own format: VMware use the VMDK and Microsoft & Citrix use the VHD format. Note that there could be more sub-types (for example for the VMDK files, but we will explain in future posts). To convert between different format you can use some kind of converter to perform a virtual to virtual (V2V) task.
